All I've done is removed my muffler (cat still in place). Do you have a 6.0L or are you just guessing at times? Keep in mind that I'm talking about 4x4, so there's no spinning off the line. I have one, and I know I didn't gain even a tenth of a second removing the muffler. It runs high 14s stock, mid 15s with a 2wd. If you have a vehicle that runs a 15.0 flat, let me know, and I'll tear you up with nothing done to my truck except removing the muffler. I've seen dynos that say removing the muffler adds 2hp. I didn't do it for speed, just so I can hear the turbo spool up better. It sounds better to me. Not a big performance gain by any means. But I'll sit side by side with a Mustang GT stock!
Really it isn't what the original poster was asking, but a couple people posted that because of the weight it couldn't get there, and my truck weighs double what my wife's JGC does and willl run 3 seconds faster than her in a 1/4 mile. If you live in the Denver area, I'll be more than happy to take you for a spin.
